+ This enables PCI Express Downstream Port Containment (DPC)
+ driver support. DPC events from Root and Downstream ports
+ will be handled by the DPC driver. If your system doesn't
+ have this capability or you do not want to use this feature,
+ it is safe to answer N.
+
+ To compile this driver as a module, choose M here: the module
+ will be called pcie-dpc.
